You can expand the expression #(m+6)^2# (although I am not sure this "simplifies" it.

#(m+6)^2 = m^2 +12m +36#

If this is all you need you can stop reading now.
If you are unsure of how this is determined, continue...

#(m+6)^2#

#=(m+6)xx(m+6)#

#=mxx(m+6) + 6xx(m+6)#

#= (m^2 +6m) + (6m+36)#

#= m^2 + 12m +36#

In general
#(ax+b)^2 = (ax)^2 + 2abx + b^2#
